Accurate Load Forecasting for Behind-the-Meter DERs: The Future of Smart Energy Management

As the Midwest’s power grid evolves to meet growing demand, aging infrastructure, and renewable energy integration, ComEd’s Supplemental Projects provide a roadmap for proactive transmission upgrades. These initiatives, aligned with the PJM M-3 planning process, highlight an urgent need for innovative electrical engineering solutions — and Keentel Engineering is ready to lead the charge.

Why ComEd’s Supplemental Projects Matter

During the March 4, 2025, TEAC Western Committee meeting, ComEd shared critical infrastructure updates across Illinois. The primary drivers behind these projects include:

  • Aging and Obsolete Equipment
  • Customer Load Growth and Interconnection Demands
  • Regional Congestion and Reliability Risks Identified by MISO

At Keentel Engineering, we recognize that expert transmission engineering is essential to delivering safe, reliable, and future-ready power systems — and we are proud to serve as a trusted partner in this transformation.
